Topic: Questions about PS1 games with 3 second pregaps,and 2 data track games

I noticed Fighter Maker (http://redump.org/disc/3246/) has a 3 second pregap. I am assuming that resizing the data track for this game is the same process as that used for a 2 second pregap, and that you just change the command line:

RESIZE -r -352800 "Track 01.bin"

to

RESIZE -r -529200 "Track 01.bin"

How do you pad the audio track for this game, since "pregap.bin" I found in a Castlevania thread here is only 352800 bytes?

My other question is about PS1 games that have 2 data tracks, like No One Can Stop Mr. Domino (http://redump.org/disc/2823/) and Street Fighter Alpha 3 (http://redump.org/disc/508/). Is the same process used for dumping the 2nd track as is used for the first track (Extract RAW Data (2352 bytes/block) (*.bin, *.iso))? And does the 2nd track need to be padded with the pregap.bin file?

I didn't see any other threads asking about this so hopefully I'm not asking something that was already asked before.

This pregap.bin file is a simple dummy file of 352800 bytes, for 3 seconds simply create a dummy file of 529200 bytes and use this instead! Same Principe is for other pregap sizes.

Yes, extract the second track as the first one, but you can't simply use here the dummy pregap, because it is not a audio data, and the second data track contains data in this section and you have to move thus 2 seconds from the end of the first track to the beginning of the second. You better use "reMove" tool for this operation, it works fine

And, you must be sure that this gap data is actual a pregap and not postgap, we would also need the subchannels to find it out...

Cool! Thanks a lot. I wasn't aware of those tools and threads, or that psxtools had other options besides just the FIX option (the readme file doesn't mention any commands other than ones that got removed). I'll have a look at that stuff n maybe I can make that ps1redumper I posted a little better.:)

Oh My drive actually refuses to read the audio pregap as a part of the datatrack, so I don't have such a problem and kinda forgot about it Anyway, simply padding everything with zeroes isn't a very good idea, imo.

Re: Questions about PS1 games with 3 second pregaps,and 2 data track games

During my very interesting journey of converting p2p to redump, I've come upon some audio tracks with data in the pregap. Usually the first couple of bytes in a sector that I see so much on the data tracks. I thought they were fine since they matched, so I never said anything. Also, I've come upon some audio tracks with the Riff header in them (which AFAIK means wave format), but they also matched the database so I didn't say anything. I forgot which dumps were those though..

If its not normal, let me know so I could make a note of it from now on.

This is something most than common for all other systems, I talk about first audio track (only PR reports data if there's something or if you simply dump with wrong offset, EAC pad everything with 0x00) and expecially about discs with only one audio track the ones you normally pad.
